Hi,

is it possible to trigger any kind of customized diagnosis alarm using the Profinet IRT gateway module ? The user manual only states in section 5.4.2 that the gateway sends a pre-defined diagnosis alarm to the controller when the communication is interrupted.

Is there any way to define an own ...

Increase Output1 (which corresponds to Input__1 of the Profinet IRT gateway) every 1 s.
Output2 mirrors ...

Dear Ulrich,

To be more clear with my questions:

What is the minimum latency which can be ...

Hello Sven,

Thank you very much for your reply. I like your idea to measure the latency directly on the RevPi.
I just want to get the idea right concerning your statement "It should receive the Profinet packet via its network interface". Right now, the Profinet communication is between my Profinet ...

Hi,

I am wondering what the merits and demerits of these two setups are:



Using a RevPi Connect with Codesys license as Profinet device . No Profinet IRT Gateway.



merits: no Gateway needed, no need to transfer data (process image) between RevPi and Gateway (would it be faster/have less ...

Hi,

I am using a RevPi Core S and the Profinet IRT gateway. In order to examine latency issues which I am facing, I did the following:

In the RevPi, the revpimodio2 cycleloop() is running with a cycletime of 5 ms. As soon as Input__5 is set to 5, I am sending a ping from the RevPi to my PC ...
